Application filed llpril 26', 1900.

To all whom it may concern:

Be it known that I, WILLIAM S. BIDLE, a resident of Cleveland, in thecounty of Guyahoga and State of Ohio, have invented certain new anduseful Improvements in Methods of Manufacturing or Forming Forked Eyebars; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use the same.

My invention relates to an improved method of manufacturing or formingforked eyebars.

The object of this invention is to simplify and facilitate themanufacture of bars of the character indicated and to produce a forkedeyebar that is lighter, cheaper in construction, and more durable thanthe forked eye bars heretofore made.

WVith this object in view the invention consists in certain stepsemployed in the manufacture of my improved eyebars hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure I is a side View of a billetemployed in the formation of the blank that is required for themanufacture of my improved eyebar, and Fig. II is an end view of thesame. Fig. III is a top or bottom View of the blank, and Fig. IV is aside view of the same. Fig. V is a side view of the bar-forming forgingmade from the blank illustrated in Figs. III and IV, and Fig. VI showsaside edge. view of the said bar. Fig. VII shows the manner ofassembling the halves or sections into which the bar illustrated inFigs. V and V1 is divided, and Fig. VIII shows the said assembledsections welded together and converted into my improved eyebar. Fig. IXis a section on line IX IX, Fig. VIII, looking in either direction. Fig.X is an end elevation, in central section, of apair of rolls employed inrolling a billet into the shape required to form a blank suitable foruse in the production of my improved eyebar. I Fig. XIis a side Q16".vation of the said rolls. Fig. XII is a transverse section on any one oflines XII XII, Figs. X and XI. Fig. XIII shows a pair of dies operatingupon one end portion of the blank. Fig. XIV is a vertical section online XIV XIV, Fig. XIII. Fig. XV is a vertical section on lines XV XV,Fig. XIII. Fig. XVI

is a top plan of the lower die. Fig. XVII is a vertical section on lineXVII XVII, Fig. XVI. Fig. XVIII is a bottom plan of the upper die. Fig.XIX is a section on line XIX XIX, Fig. XVIII.

Figs. I and II show the billet a that is rolled into the shape requiredto form the blank I) employed in theproduction of my improved -eyebar,aud Figs. III and IV illustrate the web b 'contains the material thatforms the shank of the finished eyebar, and the thinner or end portionsof the web form the necks that connect the eyes of the finished eyebarwith the shank of the bar. The web b is provided upon each side withribs b arranged transversely of the web and at suitable intervalslongitudinally of the web.

Figs. X, XI, and XII illustrate the parallel rolls a employed in theformation of the blank. The rolls are arranged horizontally one directlyabove the other and supported from housings or standards (not shown) inany approved manner. ,Each roll upon its peripheral surface is providedwith a channel c, that extends circumferentially of the rolls a suitabledistance. The end portions 0 of the channel of each roll have greaterdepth than the remaining or central portion of the channel, and theheads of the blank are formed within the said deeper portions of thechannels of the rolls. The web of the blank is formed within the centralor shallower portion of the channels of the rolls, and the end portions0 of the central or shallower portion of the channel of each roll aresomewhat raised, as required, to form the thinner portion of the webnext to the heads of the blank. The central outwardlyfacing wall of thecentral or shallower portion of each channel 0 is provided with grooves0 that extend transversely of the said wall and are arranged at-suitableintervals longitudinally described. The rolls rotate during theiroporation in the direction indicated by the arrows 01 in Fig. X, andeach roll at the receiving end of its work-receiving channel is providedwith a stop-forming shoulder that forms an abutment for the workpreparatory to the rolling operation, and the billet or work is pushedand held against the said abutment c of the two rolls until the rollshave commenced to operate upon the billet.

The blank illustrated in Figs. III and IV having been formedin themanner hereinbefore described is operated upon between the cooperatingdies, (illustrated in Figs. XIII to XIX, inclusive,) and the cooperatingsurfaces of these dies have the form required to render them capable ofoperating upon each end portion or half of the blank at a time and forgethe blank into the bar 6. (Illustrated in Figs. V and VI.) The blank iselongated during the forging operation and the forged article is a barthat terminates at each end in a circular head e, having each sidethereof provided centrally with an indentation e and having theindentations in opposite sides thereof in line, and the bar 6 has itscentral portion, centrally between the heads 6, increased in thickness,asat c and provided with beveled ends 6, sloping toward each other fromthe thinner end portions of the bar, and the edges of the bare aresomewhat beveled, as illustrated, chiefly to facilitate the removal orseparation of the bar from the dies. The lower die f of the forging-dieshas a plain horizontal top surface and is provided centrally of the saidsurface with a channel f, that in length and general configurationcorresponds to one-half of the length of the bar 6 that is to be formedby and between the dies, and the said channel, as illustrated in Figs.XVI and XVII, is open at one end thereof, as at f at one end of the dieand has has its other or inner end enlarged and forming a circularchamberf whose bottom is 1 provided centrally with a conical projectioning to the channel f, formed in the lower diethat is, the projectingpart h of the upper die has a circular end portion 71 arranged to enterand conform to the circular portion f of the channel of the lower die,and the remaining portion of the said projeccapable during the forgingoperation of entering the channel of the lower die next to the circularportion of the said channel, but not long enough to extend to the outerend of the channel, so that the thinner portion of the resulting bar orforging 6 shall be formed between-the dies within the circular portionof the channel of the lower die and in the inner end of the straightportion of the said channel, as shown in Fig. XIILand obviously as theprojection of the upper die does not during the operation of the diesextend into the outer end of the channel of the lower die the thickerportion of the resulting forging is formed within the outer end of thestraight portion of the said channel. The dies, when they have operatedupon one end portion of the blank, are separated to permit the removalof the blanks end half that has been operated upon from the dies,whereupon the work is turned end for end and returned with its other endto be operated upon by and between the dies. Figs. XIII, XIV, and XVshow the diesopcrating upon an end half of the blank I). The

bottom of the circular portion of the channel of the lower die isprovided centrally with a conical projection f adapted to form theindentations in one side of the bar 6 during the operation of the dies,and the projecting portion h of the upper die has its circular endprovided centrally with a conical projecting member h capable of formingthe indentations in the other side of the bar e during the operation ofthe dies. The side walls of the channel of the lower die and the edgesof the projection of the upper die are beveled or sloping, as required,to render them capable of forming the beveled edges of the resultingbare. The bar 6 having been formed is severed centrally andtransversely, so as to divide the bars into halves centrally of thecentral and thicker portion of the bar, whereupon the resulting halvesare assembled, so that their heads register with each other, as shown inFig. VII, with the thicker or offset portion 6 of each half against andarranged longitudinally of the offset portion 6 of the other half, so asto form a fork, whereupon the thicker and offset portions 6 of theassembled halves are welded together upon the application of heat in anyapproved manner, so as to form the shank Z of the resulting forked barZ, (illustrated in Figs.VIII and IX,)

and the indentations e of the parts assembled in Fig. VII are enlargedinto perforations Z in the finished eyebar.

What I claim is- 1. An improvement in the manufacture of eyebars hereindescribed, consisting in forging a blank into the form of a bar providedwith head-formin g ends and thicker centrally between the head-formingends, then severing the bar centrally and transversely of the centraland thicker portion of the bar, then as-. sembling the resulting halvesor pieces with their offset or thicker portions abutting each other andwith their head-forming ends in registry, and then welding together thesaid abutting ends of the assembled sections, substantially as and forthe purpose set forth.

2. The method herein described of converting a billet into a forkedeyebar, consisting in rolling a billet into the form of a blank havingits ends terminating in heads connected by a web enlarged in thicknesscentrally between the heads, then forging and elongating the blank so asto form a bar having head-forming ends and thicker centrally between theheads, then severing the said bar transversely centrally of the thickerportion of the bar, then assembling the resulting sections or pieceswith their head-forming ends in registry and with their offset orthicker ends abutting each other, and then welding together andelongating the abutting .ends of the assembled sections, substantiallyas and for the purpose set forth.

3. The formation of a forked eyebar from a billet a, by, first, rollingthe billet into a blank I) having each end terminating in a head I) andhaving a web 19 connecting the heads and enlarged in thicknesscentrally; secondly, forging the said blank into a bar 6 having its endportions thinner than its central portion and terminating in circularheads 6 provided with the indentations e thirdly,severing the said barcentrally and transversely; fourthly, assembling the resulting sectionswith their thicker ends abutting each other and with their indentedheads in registry; fifthly, welding the said thicker ends together andthereby forming the shank of the eyebar, and enlarging the indentationsof the heads into perforations that register with each other and therebycompleting the formation of the eyes of the eyebar, substantially as setforth.
